Abstract

While recent advances in intracortical brain-computer interfaces (iBCI) have demonstrated the ability to restore motor and communication functions, such demonstrations have generally been confined to controlled experimental settings and have required bulky laboratory hardware. Here, we developed and evaluated a self-contained portable iBCI that enabled the user to interact with various computer programs. The iBCI, which weighs 1.5 kg, consists of digital headstages, a small signal processing hub, and a tablet PC. A human participant tested the portable iBCI in laboratory and home settings under an FDA Investigational Device Exemption (NCT01894802). The participant successfully completed 96% of trials in a 2D cursor center-out task with the portable iBCI, a rate indistinguishable from that achieved with the standard laboratory iBCI. The participant also completed a variety of free-form tasks, including drawing, gaming, and typing.

便携式皮质内脑机接口的演示
虽然皮层内脑机接口(iBCI)的最新进展已经证明了恢复运动和通信功能的能力,但这种证明通常局限于受控的实验环境,并且需要笨重的实验室硬件。在这里,我们开发并评估了一个独立的便携式iBCI,使用户能够与各种计算机程序进行交互。iBCI重1.5公斤,由数字前置台、小型信号处理中心和平板电脑组成。一名人类参与者根据FDA研究器械豁免(NCT01894802)在实验室和家庭环境中测试了便携式iBCI。参与者使用便携式iBCI成功完成了96%的2D光标居中任务,这一比例与使用标准实验室iBCI的比例没有区别。参与者还完成了各种自由形式的任务,包括绘画、游戏和打字。
